<p>Water supplied to an evaporative cooler is treated by a number of successive steps, comprising (1) water conditioning by an electromagnetic radiation field, preferably in the radio frequency band; (2) the conditioned water is passed through a heat exchanger; (3) the water is passed to a first dispersion means whereby the water is formed into small droplets which fall, under the action of gravity directly or through one or more baffles, to a collection reservoir where the suspended solids are able to settle under the influence of gravity to a sump; (4) the supernatant water is returned from the reservoir to the water heat exchanger; (5) the sump contents is passed to a series of filters and through an electrolytic biocidal cell to a second dispersion means operating as described previously.</p> |
